\cf0 Dec. 13, 2016 \'96 The Arctic saw the warmest temperatures ever recorded in 2016, according to an\'a0annual report\'a0released Tuesday by the National Oceanic and Atmospheric Administration.\
Air temperatures were 2\'b0C (3.6\'b0F) higher than their 1981-to-2010 average in\'a0the months between October 2015 and September of 2016. That time period coincided with a strong El Ni\'f1o event, NOAA reported. According to the agency, since 1900, temperatures have risen even more than that\'a0in the Arctic: 3.5\'b0C (6.3\'b0F). All this means temperatures in the region continue to climb at double the rate of the planet as a whole.\
\'93The average surface temperature in the Arctic, from January until September of 2016, was by far the highest we\'92ve observed since 1900,\'94 said Jeremy Mathis, who directs NOAA\'92s Arctic Research Program. \'93And this is a critical point, there were record temperature highs set in January, February, October, and November of 2016.\'94\
\'93The story in the Arctic has been warming in the summertime, you have this big loss of sea ice in the summer\'85 but now we\'92re seeing temperature records being shattered in the wintertime,\'94 Mathis continued. \'93And so we\'92re seeing that this persistent heat is now staying around year round. The fact that we\'92re breaking temperature records on the warm side in the winter months is what\'92s really indicating that these trends are what\'92s here to stay.\'94\
The report, which is peer reviewed for its statements up through September, included\'a0a special non-peer reviewed addendum to cover the months of October and November of 2016 \'97 perhaps because they were so extraordinary, featuring record low levels of Arctic sea ice heading into deep winter. (The Arctic is the region of the planet north of 60\'b0latitude.) Here, the document noted the \'93record breaking delay in the freeze up of the sea cover in Fall 2016 is associated with unprecedented warm air and ocean surface temperatures.\'94\
In 2016 overall, warm Arctic temperatures led to the 2nd lowest level of Arctic sea ice ever recorded at the summer minimum in September. Many individual months saw all-time record lows. 2016 saw the 2nd earliest beginning to the melt season for the Greenland ice sheet, low snow cover, and much else.\
\'93The 2016 Arctic Report Card further documents the unraveling of the Arctic and the crumbling of the pillars of the global climate system that the Arctic maintains,\'94 said Rafe Pomerance. He is chair of the group Arctic 21 and sits on the Polar Research Board of the National Academy of Sciences. \'93Governments must urgently work together to establish a future Arctic that minimizes ever greater warming from the loss of sea ice and snow cover and thawing permafrost, and massive sea level rise from the shrinking Greenland ice sheet and other Arctic glaciers.\'94\
One of the most watched \'97 and most controversial \'97 aspects of this rapid Arctic change involves the jet stream. There\'92s a prominent theory, advanced by Rutgers University\'92s Jennifer Francis, that the decreasing temperature difference between the Arctic and the mid-latitudes as the Arctic warms is slowing this stratospheric air flow. That causes it to take a more elongated and loopy path, which can in turn lead to more weather extremes, as weather systems become stuck in place for longer periods.\
NOAA isn\'92t officially endorsing this theory yet, but it is\'a0studying it closely, Mathis said. \'93As the Arctic destabilizes, these cold air masses can start sliding down into the lower 48. That can give us extreme weather,\'94 he said.\
All of this is happening due to global warming resulting from the buildup of CO

\fs24 in the atmosphere. But in the Arctic itself, the NOAA report notes, permafrost soils currently contain twice as much buried carbon as resides in the air. One of the most striking parts of the NOAA report is that this region \'93appears to be releasing net carbon to the atmosphere,\'94 even after an increase in plant growth in the Arctic that partially offsets soil losses.\
The news about the record warm Arctic comes as President-elect Trump has named Rex Tillerson, the chief executive\'a0of ExxonMobil, as his secretary of state. As head of the world\'92s largest private oil company, Tillerson and Exxon \'93had begun a drilling program in the Arctic\'92s Kara Sea, where Exxon made a find, and had agreed to explore shale oil areas of West Siberia and deep waters of the Black Sea,\'94\'a0note\'a0Steven Mufson and 2
\i Washington
\i0 Post colleagues today. But this was halted by sanctions on Russia.\
The irony is that, if Arctic drilling goes forward, the resulting fossil fuels will surely make global warming even worse. But global warming, by reducing the amount\'a0sea ice, will also have also made drilling easier to pull off.\
